He topped off a venti vanilla bean frap. with a whooping 60 shots of espresso, mocha, white mocha, protein powder and drizzles of caramel, hazelnut and more mocha to transform it into a Sexagintuple Vanilla Bean Mocha Frappuccino measuring 128 ounces.

The $54.75 drink was so large Chafari had to bring in his own vase for bemused baristas to make it in.

"The recipe was just the best sounding thing I could think of that would make 50+ shots drinkable," said Chifari via email about his effort which took a level of planning and engineering perhaps worthy of his Rice background.

"Since it was going in a glass vase, it had to be cold so I could carry it without burning myself. And I knew I couldn't drink it all at once, so a drink over ice would get diluted when the ice melted so that was out," said Chifari who is now based in Dallas.

It actually took 5 days to drink in the end with some warning the level of caffination ingested from 60 shots is halfway to what is considered a lethal dose.

Chifari said there were many issue with the "drinkability" of that drink, i.e. it tasted gross, and that his aim was to make something that was at least halfway decent."It was delicious. It tasted like really sweet strong coffee. Similar to Vietnamese iced coffee," he said.

Previous creations from the Mathematics and Linguistics major include the El Nino giant Taco pizza which totaled three pounds.

According to Chifari that ended up being featured in a Groupon ad.

But the best thing about the mega venti frappaccino has to be that is was completely free with the $54.75 covered by Chifari's Starbucks reward card.
